Ultra-high power electrode graphite

Ultra-high power electrode graphite
Product Detailed
Made from imported needle coke Current density: 25 A/cm2 min.

Introduction

The graphite electrode is made of highquality petroleum coke or imported needle coke. It is widely used as electrode in electric ark furnace for the producing of alloy steel,other non-ferrous metals or nonmetallic materials.The Diameters range is 50-500mm and the length range is 1000-2000mm.

Advantages

-low electrical resistance

-excellent resistance to oxidation, thermal and mechanical shock

-high electric and thermal conductivity

-high mechanical strength

-fine machining accuracy
